Problems solved by technology

[0004] In the existing CVD preparation process of graphene, the graphene growth substrate is generally placed directly inside the quartz tube, and the graphene growth substrate is easily deformed at high temperature, and adheres to the quartz tube wall, resulting in a reduction in the yield of graphene; due to The space of the heating equipment is limited, which limits the size and quantity of graphene films grown at a time, and the space utilization rate of the existing heating equipment is not high, resulting in a waste of resources

Description

technical field [0001] The invention relates to the technical field of graphene preparation, in particular to a fixture for multiplying graphene preparation and a graphene preparation method. Background technique [0002] Graphene is a honeycomb single-layer carbon material composed of carbon atoms according to sp2 hybridization bonds. Its special crystal structure endows graphene with many excellent physical properties, such as room temperature quantum Hall effect, high carrier mobility, high thermal Conductivity, long-range ballistic transport properties, etc. These excellent physical properties make graphene one of the most promising electronic materials. [0003] At present, the methods for preparing graphene mainly include mechanical exfoliation, SiC crystal epitaxial growth, graphite oxide reduction and chemical vapor deposition on transition metals. The mechanical exfoliation method is mainly used in the laboratory to prepare high-quality graphene samples, but the p...
